So I bought a Verizon LG G3 about a month ago off of someone. However,I wasn't aware that the phone was rooted - which I'm guessing is in order to unlock the phone (I currently have T-mobile service). Now, I know pretty much nothing about rooting and such. Jailbreaking iproducts sure, but not rooting. I have no need or want for the root except for the unlocking aspect of it. And with the Marshmallow update coming in, I'm not sure how that will interfere with the root on my phone.

Question is, can simply unrooting the phone re-lock my device? The only reason I'm keeping the root around is so that it remains unlocked. I've tried looking around the internet but only found things on factory resets and whatnot

If the phone is unlocked from the carrier, unrooting the phone will not undo that change. If you want to ensure that your phone is unrooted, you can probably check LG's website and see if they have factory images for their phones so you can revert to an unrooted, vanilla state.

Thanks for all the replies! However, I'm not exactly having trouble with the unrooting part perse. I have SuperSU and it's as simple as just pressing the button that says "full unroot".

My question was that if I were to unroot my currently rooted, unlocked phone, would it relock it? I'm not sure if it's unlocked because the previous owner had unlocked it with the company or whether he used rooting to unlock it. Is there a way to find out whether it had been normally unlocked or by the root? It's a Verizon phone with T-mobile service currently. I don't want to flash the phone to a factory state as I think that would lock the phone again.

Not likely, if the phone has been unlocked using a hack (I don't know if this is even possible on Android devices) it's likely part of the ROM/radio firmware or similar, not a separate app that would require su. In that case updating to stock firmware would probably re-lock it though. But it's most likely a normal unlock.

Thanks so much! I thought it wouldn't re-lock but I'm a noob with android so I wasn't sure. About to unroot hopefully with success~

As far as I know rooting andnunlocking are two entirely separate things. I've rooted phones before (heck my current phone is rooted, did it myself) it was a factory unlocked phone too, but the rooting was done by myself (using existing tools and exploits by others of course ). From what I understand (been a droid user for several years now) rooting doesn't help in unlocking the phone at all, at least from my experience. You should be fine if you unroot it. It should remain unlocked after...

Generally speaking, the bootloader and the ROM are two separate things. The basic function of rooting is just changing permissions on the ROM and adding in the SU binary, the bootloader is untouched. Unrooting won't touch the bootloader, and even installing OTA updates won't touch the unlock status in the bootloader.

As long as you don't re-lock it yourself, you should have no issues when unrooting and such.
